1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Rough contacts are ubiquitous, yet the impacts of the roughness matching on frictional behavior remain insufficiently understood. We investigate how slow shear and stick-slip transition depend on the roughness alignment between contacting surfaces. By rotating one surface with respect to the other, we precisely control roughness matching, enabling nearly an order-of-magnitude variation in the maximum static friction coefficient. Both the variation amplitude and the angular range over which the frictional strength varies are governed by roughness alignment. Universal statistical patterns emerge in micromechanical quantities, including the microcontact area, orientation, deformation, and their evolutions under shear, following generalized extreme value distributions. To quantify asperity interactions, we introduce the contact fabric tensor, whose anisotropy provides a unified measure of roughness matching and a predictor for frictional strength and sliding onset. These findings advance our understanding of friction at rough interfaces and inform the design of mechanical systems, adhesives, and fault models.
